WlNDOW-SASH.

EBPECIFICA'IION forming part of Letters Patent No. 333,438, dated December 29, 1885.

Application filed January 9, 1885. Serial No. 152,376. (No model.)

To all whom it may concern.-

Be it known that I, LoUIs L. ARNOLD, of Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Window-Sashes, of which the following is a specification.

This invention relates to improvements in the window-sashes for which Letters Patenthave been granted to me heretofore, numbered 299,944. dated J one 10, 1884; and the invention consists of a window-frame having detachable partingstrips and front stop-bead and fixed pivots at the lower corners, and sashes having recessed plates at their lower corners and longitudinal recesses in the upper part of their side rails, said recesses having fixed hooks at their lower ends for engaging the loop-shaped ends of the detachable sashcords. The parting-strips are connect-ed to the window-casing by means of a covered slide-bolt, which engages a staple of the parting-strip and is engaged at its forked front end by the T-shaped lug of the front stopbea d, which latter engages the slide-bolt and moves it into position for looking or releasing the beads.

In the accompanying drawings, Figure 1 represents a vertical transverse section of a window-casing with my improved sashes, shown-in lowered position. Fig. 2 are details showing the connection of the sash-cords with the sash. Figs. 3, 4., and 5 are details ofthe means by which the removable stop-beads and parting-strips are held in place, and Figs. 6, 7, and 8. are details showing the connection of I the sashes wit-h the window-casing.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the window-casing, and a a a, respectively, the rear stop-bead, parting-strip, and front stopbead. The lower halves of the parting-strips a and front stop-beads, 0. are removable, they being attached to the casing by means of aslide-bolt, b, that is made tapering at the rear end and forked at the front end, as shown in Figs. 3, 4, and 5. The tapering rear end engages a staple, 1), arranged in a recess of the parting-strip a, while the forked front end of the bolt b is engaged by a T-shaped lug, d, of the front stop-beams".

The slide-bolt b is when the front bead is detached from the window-casing.

To detach the parting-strip a and front bead, a from the window-casing, the front bead, a is taken hold of and moved forward, so that the lug d carries the slide-bolt I) along until the forked end of the same is back of the' recess of the plate N. The lug can then clear the T-shaped recess, so that the front bead, a", can be detached from the window-casing. As

the bolt 1) has also released the staple b of the parting-strip a, the latter can also be re moved.

The sashes B B are provided in their side rails with recesses e e for the sash-cords O O,

the recesses being made of greater length than the recesses for the sash-cords in common.

sashes. e of the side rails of the sashes B B are The upper rear corners of the recesses rounded off, as shown in Fig. 1, to facilitate the ready passing of the sash-cords in or out of the recesses. The sash-cords O O are connected detachably to the enlarged lower ends of the recesses e e of the sashes by means of an eye, f, formed at the ends of the sashcords, which eyes f are attached to hooks f in said recesses, as shown clearly in Fig. 2.

The recesses e e are made of the length described for the purpose of permitting the swinging down of the sashes B B into a horizontal or nearly horizontal posit-ion after the lower sections of the parting-strips and front beads have been removed. The increased length of the sash-cord recesses brings the connection of the sash-cords and sashes to a point somewhat below the middle of the sashframe, so as to descrease the length of the sash-cords and prevent the balance-weights from reaching the bottom of the sash-boxes when the sashes are raised. The lower' ends of the sashes B B are pivoted to the windowcasing A, the pivot-connection being shown in detail in Figs. 6, 7, and 8. It consists of a fixed pivot, g, provided with diametrioal lugs g, which engage a recessed corner-plate, 9',

sash-frames, and a loop tied into the cords,

upon which they are released, so that the balance-weights are allowed to drop as far as the loop will permit. The sashes are then placed, one after the other, in a nearly vertical position,so that the slotted corner-platesg clear the lugs g and permit the removing of the sashes. The sashes can then be cleaned or repaired,

. as required. They are placed'in the reverse order. The sashes may also be cleaned when in lowered position, as shown in Fig. 1.

My improved sash-construction has the advantage that the sashes can be swung with great facility into lowered posit-ion for cleaning without requiring the bending out of the window or otherwise exposing the person who cleans the window to danger.

Old sashes can be readily changed, at a small expense, to my improved construction, as all that is required is to elongate the recesses of the sash-cords, apply the pivot-connections, and make the parting-strips and front beads removable.

In cleaning the sashes both sections are first cleaned at the inside, after which the lower sash is lowered and cleaned at the outside. The upper sash is then lowered, first cleaned at the inside, and swung down on the lower sash and cleaned at the outside, after which the sashes are returned into their proper The recessed plate isposition. The sashes may also be entirely detached from the sash-cords and windowcasing, particularly when a thorough cleaning, painting, or repairing of the same is required.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination of a window-casing having detachable parting-strips and front stop-beads and fixed pivots at the lower corners, sashes having recessed plates at their lower corners and longitudinal recesses in the .upper parts of their side rails, fixed hooks located in the lower enlarged parts of said recesses, and detachable sash-cords having loopshaped ends, substantially as set forth.

2. The combination ofa window-casinghaving detachable parting-strips and front stopbeads and fixed pivots with diametrical lugs with sashes having recessed corner-plates and interior stops and sash-cords attached detachably to the grooves of the sashes, substantially as set forth.

3. The combination of a window casing having a horizontal recess, of a detachable parting-strip having a staple, a detachable frontbead havingalocking-lugandaslidebolt having a recessed front end engaged by the lug of the frontbead and adapted to be moved backward or forward by the latter, so as to engage or to release the staple of the partingstrip, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
